IMPROVEMENT IN GRAI N-SEPARATORS.

Specification forming part of Letters Patent No. 41,011, dated December 22, 1863.

To aZZ whom it may concern.-

Beit known that I, BENJAMIN S. HYERS, of Pekin, Tazewell county, Illinois, have invented a new and useful Improvement n VVinnowing Machines; and I do here by declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure l is a perspective view of my machine as adapted for separating oats from wheat. Fig. 2 is alongitudina-l section of the same. Fig. 3 is a longitudinal section of my machine as adapted for separating chess, cheat, cockle, &c. Fig. at is a detached view representing the device for adjusting the pitch of the screens, 81c.

A represents the rear part of the frame of a winnowing-machine.

B represents a shoe suspended at front to the frame by a single hook-and'staplejoint, G, and at back by means of two rods or links, D, one each side.

The grain is received from the hopper on a chute, E, a central protuberance on which causes the grain to flow to either side onto a riddle, F, which carries off the chafi and other coarse refuse, and permits all the grain, whether large or small, to drop onto the screens below. The heavier grains of wheat descend at 1 in front of the short screen G while the oats and all the lighter ofi'al are carried by the blast onto the short screen G, and escape over the rear edge of said screen at 2. This action of the wind upon the lighter grain is assisted by a deflector, H, secured to the shoe sides by means of bolts h. Sand and like refuse are separated by the bottom screen, I. The screen I, requiring special adjustment and agitation, its rear edge is supported on an adjustable ledge, J, while its front edge is supported upon arms K, which project from a rock-shaft, L, having a counter-arm, M, connected by pitman N to the frame at O. The effect of this arrangement is to give the bottom screen a special longitudinal and vertical agitation in addition to the laterally-swaying motion of the shoe itself.

For cleaning wheatin which chess and cockle abound I remove the short screen G and securing the deflector H to the position shown in Fig. 3, I attach thereto a chess-board, P. This arrangement brings a strong draft to bear upon the chess and cheat, so as to blow these materials out at the rear of the machine at 2, while the wheat falls down in front of the screens at 1.

To enable the adjustment of the screens and chess-board to any pitch that may be desired I provide cleats Q, capable of adjustment upon, or over, or under pins R. The cleats Q slide and rest within grooves S in the shoe-frame, and when adjusted over the pins It the latter rest in notches T in the shoe-frame.

U is a latch-plate, which, being engaged over the studs V, holds each screen in its proper groove. The front and rear inner edges, W X, of the screen frames, beingbeveled, respectively, outward and inward in the manner shown, avail the entire screen'surface to the action of the blast.

I claim herein as new and of my invention- 1. The pivoted strips Q, applied tothe edges of a riddle, screen, or chute-board, when used in the described combination with pins R or any other suitable device to support one end of the said riddle, screen, or board, at any desired height.

2. The latch U V, constructed substantially as described, and employed to retain the riddles within the shoe or permit their ready removal, as desired.

3. The combination of .the rock-shaft L, arms K M, and rod N, operating in the manner explained to impart longitudinal and vertical motion to the screen I within the shoe by the lateral motion of. the latter.

4. The adj ustalble and removable deflectingboard H, attached to the shoe B by bolts h h, in the manner and for the purposes explained.

In testimony of which invention Ihereunto set my hand.
